LED LED ikeneye itara ryinyuma?

Kimwe mubibazo bikunze kubazwa kubyerekeranye na LED ni ukumenya niba bakeneye itara ryinyuma. Gusobanukirwa itandukaniro riri hagati yubuhanga bwerekana ni urufunguzo rwo gusubiza iki kibazo, nkubwoko butandukanye bwa ecran, nka LED na LCD, bukora kumahame atandukanye. Muri iyi blog, tuzasesengura uruhare rwo kumurika inyuma muburyo butandukanye, kandi byumwihariko niba LED ibishaka cyangwa idakeneye.

1. Kumurika ni iki mu kwerekana?
Kumurika inyuma bivuga urumuri rukoreshwa inyuma yumwanya wo kumurika ishusho cyangwa ibirimo bigaragara. Mubihe byinshi, iri soko ryumucyo rirakenewe kugirango ecran igaragare, kuko itanga urumuri rukenewe kuri pigiseli kugirango yerekane amabara namashusho neza.

Kurugero, muri LCD (Liquid Crystal Display) ya ecran, kristu yamazi ubwayo ntabwo itanga urumuri. Ahubwo, bashingira kumuri yinyuma (gakondo fluorescent, ariko ubu LED) kugirango bamurikire pigiseli inyuma, ibemerera kwerekana ishusho.

2. Itandukaniro ryibanze hagati ya LED na LCD
Mbere yo gukemura niba ecran ya LED ikeneye urumuri rwinyuma, ni ngombwa gusobanura itandukaniro riri hagati ya LCD na LED:

LCD Mugaragaza: Ikoranabuhanga rya LCD rishingiye kumuri yinyuma kuko kristu yamazi ikoreshwa muribi byerekanwa ntabwo itanga urumuri rwabo. Mugaragaza LCD igezweho ikunze gukoresha amatara ya LED, biganisha ku ijambo "LED-LCD" cyangwa "LED-inyuma LCD." Kuri iki kibazo, "LED" bivuga isoko yumucyo, ntabwo ikoranabuhanga ryerekana.

LED ya LED (LED Yukuri): Mubyukuri LED yerekana, buri pigiseli ni diode yihariye itanga urumuri (LED). Ibi bivuze ko buri LED itanga urumuri rwayo, kandi nta tara ryinyuma risabwa. Ubu bwoko bwa ecran busanzwe buboneka hanze, ibyapa byamamaza, hamwe nurukuta rwa videwo.

3. Ese LED LED ikeneye itara ryinyuma?
Igisubizo cyoroshye ni oya - ecran ya LED ntabwo ikeneye itara ryinyuma. Dore impamvu:

Kwiyerekana-Kwiyerekana: Muri LED yerekana, buri pigiseli igizwe na diode ntoya itanga urumuri rutanga urumuri rutaziguye. Kubera ko buri pigiseli itanga urumuri rwarwo, ntihakenewe isoko yinyongera yumucyo inyuma ya ecran.

Itandukaniro ryiza hamwe nabirabura byimbitse: Kuberako ecran ya LED idashingira kumuri yinyuma, itanga ibipimo byiza bitandukanye kandi birabura byimbitse. Muri LCD yerekana n'amatara yinyuma, birashobora kugorana kugera kubirabura nyabyo kuberako itara ryinyuma ridashobora kuzimwa rwose mubice bimwe. Hamwe na LED ya ecran, pigiseli imwe irashobora kuzimya burundu, bikavamo umwirabura nyawo kandi wongeyeho itandukaniro.

4. Porogaramu zisanzwe za LED Mugaragaza
Mugaragaza LED nyayo ikoreshwa muburyo butandukanye bwo gukora cyane kandi nini-nini ya porogaramu aho umucyo, itandukaniro, n'amabara agaragara ari ngombwa:

Icyapa cyo hanze LED Icyapa: Ibinini binini bya LED byo kwamamaza no kwerekana ibimenyetso bya digitale birakunzwe kubera ubwinshi bwabyo no kugaragara, ndetse no ku zuba.

Imikino Arenas hamwe nibitaramo: ecran ya LED ikoreshwa cyane mubibuga ndetse no mubitaramo kugirango berekane ibintu bifite imbaraga bifite amabara meza kandi bigaragara neza kure.

Urukuta rwa LED mu nzu: Ibi bikunze kugaragara mubyumba bigenzura, muri sitidiyo zamamaza, hamwe n’ahantu hacururizwa, bitanga ibyerekanwa bihanitse kandi bitandukanye cyane.

5. Hari LED LED ikoresha Itara ryaka?
Mubuhanga, ibicuruzwa bimwe byanditseho "LED ecran" bifashisha amatara, ariko mubyukuri LED-yerekana inyuma ya LCD. Izi ecran zikoresha LCD ifite itara ryinyuma ya LED inyuma kugirango irusheho kumurika no gukora neza. Ariko, ntabwo aribyo LED yerekana.

Mugaragaza LED nyayo, nta tara ryinyuma risabwa, kuko diode itanga urumuri nisoko yumucyo namabara.

6. Inyungu za LED Yukuri
Mugaragaza LED nyayo itanga inyungu zingenzi kurenza tekinoroji gakondo:

Ubucyo Bwisumbuyeho: Kubera ko buri pigiseli isohora urumuri rwayo, ecran ya LED irashobora kugera kumurongo mwinshi cyane, bigatuma iba nziza haba murugo no hanze.

Kunoza itandukaniro: Hamwe nubushobozi bwo kuzimya pigiseli imwe, ecran ya LED itanga ibipimo byiza bitandukanye byo kugereranya hamwe nabirabura byimbitse, bizamura ubwiza bwibishusho.

Ingufu zingirakamaro: LED yerekana irashobora gukoresha ingufu kuruta ecran ya LCD, kuko bakoresha imbaraga gusa aho urumuri rukenewe, aho kumurikira ecran yose.

Kuramba: LED muri rusange ifite igihe kirekire, akenshi irenga amasaha 50.000 kugeza 100.000, bivuze ko ecran ya LED ishobora kumara imyaka myinshi hamwe no kwangirika gukabije mumucyo no gukora amabara.

Umwanzuro
Muncamake, ecran ya LED ntabwo ikeneye itara ryinyuma. Buri pigiseli muri LED ya ecran itanga urumuri rwayo, bigatuma ibyerekanwe ubwabyo bimurika. Iri koranabuhanga ritanga ibyiza byinshi, harimo itandukaniro risumba ayandi, abirabura byimbitse, nubucyo buhanitse. Nyamara, ni ngombwa gutandukanya ibyerekanwa byukuri bya LED na LED-isubira inyuma LCDs, nkuko byanyuma bisaba itara ryinyuma.

Niba ushaka kwerekana ibyerekanwa bifite ireme ryiza, kuramba, hamwe ningufu zingirakamaro, ecran ya LED nukuri ni amahitamo meza-nta mucyo winyuma ukenewe!
